Forbes has released its list of the top 10 highest paid Sprint Cup drivers, and it’s no surprise which driver is at the top.

According to Forbes, Dale Earnhardt Jr., NASCAR’s most popular driver, tops all drivers with an estimated income of $25.9 million. Forbes breaks down Earnhardt’s earnings into $12.9 million in salary and winnings and $13 million in endorsements.

And despite being a rookie in NASCAR’s top series, Danica Patrick also made the list with estimated total earnings of $12.9 million. Patrick, a former IndyCar star, is running her first full Sprint Cup season with Stewart-Haas Racing.

The only dollar figure Forbes has access to is the amount of purse money a driver earns in a season. Typically a driver earns 40 to 50 percent of the team’s winnings in addition to a base salary, a percentage of merchandise sales and income from personal endorsements, according to a Sporting News report last year.

Earnhardt’s season winnings last year with Hendrick Motorsports were $5.8 million, so if he gets 50 percent of his winnings, that would be $2.9 million with an estimated $10 million base salary. Hendrick’s Jimmie Johnson, Jeff Gordon and Kasey Kahne also are on the list, giving the organization four of the top 10 highest paid drivers.

Johnson, a five-time Sprint Cup champion, is second at $23 million, according to Forbes. New Sprint Cup champion Brad Keselowski is 10th at an estimated $11.4 million.

The endorsement figures are the toughest to estimate, with few deals worth more than $500,000, according to driver business managers and representatives who talked to The Sporting News last year.
